The most satisfying tap game on the App Store. Drop blocks. Build a tower. Each perfect drop triggers particle bursts, haptic feedback, and a color shift across your growing rainbow tower. HOW TO PLAY Tap to drop the sliding block onto the tower. Land it perfectly and the block stays full-size. Miss slightly and the overhang gets sliced off. Stack as high as you can before the block gets too narrow. PERFECT DROPS Nail a perfect landing and watch the block lock in with a satisfying burst of particles. Chain perfect drops for an even bigger effect. Every drop is matched with haptic feedback so you feel each landing. ZEN MODE No score. No game over. Just stack. When you miss, the block resets instead of shrinking. Build the tallest tower you want, at your own pace. GAME CENTER Compete globally on three leaderboards: Best Score, Best Height, and Best Streak.
